[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Gets a value indicating whether the Type can be accessed by code outside the assembly.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public ReadOnly Property IsVisible As Boolean

Property Value

Type: System.Boolean
true if the current Type is a public type or a public nested type such that all the enclosing types are public; otherwise, false.

Use this property to determine whether a type is part of the public interface of a component assembly.

The following code example tests two classes, only one of which is visible outside the assembly.



Friend Class InternalOnly
   Public Class Nested
   End Class
End Class

Public Class Example
   Public Class Nested
   End Class

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      With GetType(InternalOnly.Nested)
         outputBlock.Text &= "Is the " & .FullName _
             & " class visible outside the assembly? " & .IsVisible & vbCrLf
      End With

      With GetType(Example.Nested)
         outputBlock.Text &= "Is the " & .FullName _
             & " class visible outside the assembly? " & .IsVisible & vbCrLf
      End With
   End Sub
End Class

' This example produces the following output:
'
'Is the InternalOnly+Nested class visible outside the assembly? False
'Is the Example+Nested class visible outside the assembly? True
